Unusual Friendships: A Little Black Cat and A Little White Rat is a picture boo that tells the story of an unusual friendship between a black cat and a white rat. This book by Beatrice Culleton Mosionier is full of colourful Métis affectations. With subtle references to the life of a Métis, the black cat is not accepted at the cat show as he is not considered a purebred. The white rat fiddles a tune, encouraging all the cats to learn to jig. They join together and achieve status and respect for who they are. In the end, they create a new jig called the Red River Cat Dance. This story is written in a complete rhyming pattern, enjoyable for children of all ages. ATOS Reading Level: 4.6.
